Abstract: To address the instability problem in electrified railways under multi-train interconnection, this report provides a scheme for "impedance modeling - stability analysis - oscillation suppression". First, an impedance identification method for traction converters based on Artificial Intelligence (AI) is constructed. Subsequently, the stability of the multi-train interconnected vehicle-grid system is analyzed. Finally, oscillation suppression is achieved through Deep Reinforcement Learning scheme.
